Model: Skin, arterial, and lens tissue from donors between the ages of 20 and 25 and also 75 
Dosage: 5 µM solution of CMLase, incubated overnight

Bioengineered Enzyme Shows Ability to Reverse Molecular Aging in Human Tissue

An engineered enzyme reverses age-related protein damage that researchers have long thought irreversible in human eye, skin, and artery tissues.

A bioengineered enzyme reverses age-related protein damage, long thought of as irreversible damage, in human lens, skin, and artery tissues.

Basic Research

Model: Male Wistar rats 
Dosage: 1.5 g/kg/day of orally administered glycine for 5 months

Glycine, an amino acid shown to extend the lifespan of mice, moderately extends the lifespan of flies and counters brain and muscle degeneration in aged rats. 

Aging &amp; Longevity

Model: C57BL/6J mice 
Dosage: Eating only within an 8-hour window and fasting for 16 hours (~20% caloric deficit may be required)

Restricting food intake for 16 hours a day improves the health of female mice and moderately prolongs the life of male mice.

New Framework Uncovers 21 Existing Drugs with Pro-Longevity Potential

A new gene network-based framework predicts the potential of existing drugs to confer pro-longevity effects.

A new gene network-based framework predicts already-approved repurposable drugs that may either confer pro-longevity benefits or age-accelerating effects.

Model: SAMP8 mice 
Dosage: ~25 mg/kg/day of PQQ or PQI administered in food

Supplementing with the antioxidant pyrroloquinoline quinone (PQQ) modestly extends the lifespan of age-accelerated mice while improving their strength.
